The question was to design a roof system on a too small apartment with
a too low ceiling. At these kinds of places you can choose to adapt to the
existing building method or to create a design, which dissociates itself
from that.

The construction time, the transport and limited space in the street led to
the choice of prefabrication. With shells, window-/doorframes and roofing,
everything clad, glazed and decorated, a crane was installed to lift the
whole onto the roof of the apartment.
